Anyone hear if or when turtleford rally will be or and others in this area. I think sandy beach is having there rally on feb 19.

im running one of ralphs 860s. They are a good reliable engine however they do NOT build anywhere near the power that they were bragged up to be. If you own one id highly recomend someone else to dyno it. there are people doing an honest true hp port job on them. I will post his name when he is...

Does anyone have any idea when turtleford and spruce lake rally might be held this year? the snow should be good so i asume there will be one

ok, here is what i have found to work for me. primary- 200/320 SPRING, 417 RAMPS, around 20.5 ish grams at 2500 ft. so drop 4-5 g for elevation. Secondary i run a 58-38 helix and red/black spring. and dropped a few teeth on the gearing as well. geared for 100mph on the praries and will break...

not a big fan of the shockwave. poor backshift. i found it only worked decent when it was almost turned in all the ways. try some other ones they will probably work alot better. also try a cat green secondary spring.

get rid of those garbage stock secondarys. they dont backshift well at all. put on a team. lots of good combos out there.

id be interested in trying his ramps for sure. But i am strongly against the doo secondarys. They have had major problems with them for years now. I could probably get you set up very close if you were willing to dump your secondary and run a team. ive wasted alot of $$$$$$$ over the years on...

thats the name i was looking for. very good rep they have.

not trying to bash but id say talk yo a "reputabale' engine builder about mongoose before you use them. they have a rep of nikisil flaking. ive experienced it twice. most builders us an outfit out of quebec. i forget the name tho. be careful.

hey there blain. i dropped down to a 450 and when i pulled my engine apart the pistons were very black yet. i was gonna try a 430 even. pluss they are way under oiled. im gonna start adding 400ml per tank with the 860.

step #1 get rid of junk secondarys. then its at least something worth spending time and $ to get working propperly.

i will try your way first i think. looks a bit easier to get at things. its gonna be now one of ralphs 860's. looking forward to trying one of his big bores.

18mm wow. doo told me to have 15mm and i figured 16 would be better. im gonna shoot for a 32-1 ratio. lots of scuffing on most doo pistons intake side. more oil is ur friend.

your adjustment on your cable should be at about 16mm. you dont adjust them at the pump either. its about a foot back from the pump.
